摘要
本文首先在ITRF框架下利用中国国家GPSA级网的两期观测资料初步分析了中国大陆部分的局部水平形变。为了更好地和已有的地质和地球物理地壳运动模型进行比较,本文提出了一种基于先验模型的形变分析方法,得到了较为满意的结果。
The preliminary local horizontal crustal motion was estimated by using the Chinese Aorder GPS network which has been observed respectively in 1992 and 1996 based on ITRF frame. For comparison with hnown geological crustal deformation models, the priori model based method was employed to analyze the local horizontal deformation by using the above two epochs of GPS measurements. The result shows that the presentday crustal motion in China using GPS measurements is roughly consistant with the result from geologic measurements.
